Moeller window sills made of lignodur: Why is this material better than PVC??

Polyvinyl chloride from the very moment of its invention quickly received the widest application in various industries., and today it is present in the apartment of almost every person in the form of at least a window frame and a window sill. The operational properties of such a product are approximately known to everyone and are highly valued.: at a modest cost, a plastic window sill has no worse impact resistance and durability, requires minimal maintenance and is easy to clean, without absorbing pollution. Similar products are offered by dozens of different manufacturers., but still millions of consumers want buy window sill Meller.

What is the reason for increased consumer confidence in this particular brand?? The answer is simple: although his products also seem to be plastic, in fact, it is not made of PVC in its pure form, and from lignodur - a material patented by the company, which is a mixture of the same PVC with wood flour. Seems to be, obtaining a patent for a recipe in this case is not at all an empty formality - the finished mixture shows, that many other manufacturers would gladly use it in production, if not for legal protection.

Features of lignodur

We have already talked about the recipe for the material above., but the question remains open, what are the advantages of the presence of these components in the mixture?. As in other similar cases, creators, mixing ingredients, hope, that the resulting mass will retain the positive properties of all ingredients, and their shortcomings will be mutually leveled.

In the case of lignodur, this is exactly what happened.. primary goal, pursued by the inventors - to reduce the coefficient of thermal expansion of the product. For classic plastic, this figure is quite large., which means, ordinary PVC window sill can be deformed and cracked, and also provoke accelerated wear of the plaster at its junction with the wall. Lignodur products cannot but react to temperature changes at all., but in terms of volume, this is noticeably far from so strong - as a result, the room needs repairs much less often.

That's important, that such experiments have practically no effect on price - PVC window sill competitors cost about the same. This fact should not come as much of a surprise., after all, brilliant German engineers managed to improve the material by adding an ingredient, which costs next to nothing.
